That's the message I'm getting when trying to empty the trash. To my knowledge, almost all of this is just old backups from an external drive, even though the message seems to imply I've been rooting around (no pun intended) in operating system files.
Any clue what this message means?
xattr ~/.Trash/* ~/.Trash/.* | grep rootless
